    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth Akola, Maharashtra, 2019-12-16) NANDESHWAR, VIKKI NARENDRA.; Bharad, Dr. S. G.
    The present study entitled “Effect of planting geometry and fertigation levels on growth, yield and quality of chilli” was carried at University Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, during the year 2014-15 and 2015-16. The experiment was laid out in Factorial Randomized Block Design with nine treatment combination and each treatment was replicated thrice. The treatments comprised of three planting geometry (S) viz., S1 (90 cm x 90 cm), S2 (90 cm x 60 cm) and S3 (90 cm x 45 cm) and three fertigation levels (F) viz., F1 (RDF @ 150:50:50 NPK kg ha-1 through soil application), F2 (100% RDF through fertigation) and F3 (80% RDF through fertigation). An observation recorded in respect of plant growth, yield and yield attributing, biochemical parameters, available soil nutrient status, uptake of nutrients, fertilizer use efficiency, pests and disease incidence and economics of the treatments. Amongst the different planting geometry, the treatment S3 (90 cm × 45 cm) was found to be the best treatment in respect to maximum increased the growth parameters viz., plant height, stem diameter, plant spread and leaf area. Similarly, the same treatment was found best in respect of yield and yield contributing and quality parameters viz., fruit length, diameter of fruit, number of fruits per plant, average fresh weight of fruit per plant (g), green and dry fruits yield per plant (kg), yield (q ha-1), ascorbic acid, chlorophyll and crude protein contents. The fertigation level F3 (80% RDF through fertigation) was found to be the best treatment in respect to maximum increased the growth parameters viz., plant height, stem diameter, plant spread and leaf area. The yield and yield contributing characters viz., fruit length, diameter of fruit, number of fruits per plant, average fresh weight of fruit per plant (g), green and dry fruits yield per plant (kg) and yield (q ha-1) was achieved maximum by the application of 80% RDF through fertigation. Similarly, the quality parameters viz., ascorbic acid, chlorophyll and crude protein content were also found maximum in same treatment. Interaction effect of planting geometry and fertigation levels, the treatment combination S3F3 (90 cm × 45 cm + 80% RDF through fertigation) was found superior for obtaining maximum yield and better quality of chilli with higher net monetary returns and benefit cost ratio. The highest uptake of nutrients viz., nitrogen, phosphorus and potassium and maximum fertilizer use efficiency was recorded at spacing 90 cm × 45 cm along with the application of 80% RDF through fertigation (S3F3). The interaction effect between planting geometry and fertigation levels i.e., S3 F3 (90 cm × 45 cm + 80% RDF through fertigation) was found superior for obtaining maximum growth, yield and better quality of chilli with higher net monetary returns and benefit cost ratio.

    STORAGE STUDIES OF ANNONA SPECIES PULP.
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-10-07) SHRIVASTAVA, AKANKSHA.; BHARAD, Dr. S. G.
    The present investigation entitled as “Storage studies of Annona species pulp” conducted during 2017-18 and 2018-19 at Postharvest Technology Laboratory, Department of Fruit Science, Faculty of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola with the objectives of assessing the physico-chemical variations occurred in the Annona species pulp during storage alongside the variations in the sensory and physico-chemical profile of the value-added product, i.e. squash due to the stored pulp which used for the monthly preparation. Further, to ascertain the optimum period of storage up to which the quality pulp can be maintained, hence, the pulp of Annona species specifically from second-grade fruits stored under -200C temperature and the experiment laid as Factorial Randomized Block Design (FRBD) with two factors viz. species (S1- Annona squamosa L., S2- Annona atemoya) and storage duration for pulp (P0- Initial month to P8- Eighth months). The storage of Annona species pulp in the frozen form given positive results in terms of maintaining the quality of pulp with minimum losses concerning to physico-chemical and sensory characteristics. The Annona atemoya species responded comparatively better to the storage conditions than Annona squamosa L. species. The storage of the pulp at -200C temperature, retained the biochemical properties viz. sugars (total, reducing and non-reducing sugars), pH and titratable acidity in both species as evident from the non-significant variations due to interaction effect. While, the TSS, ascorbic acid, antioxidant activity and ascorbic acid content varied significantly; however, as the storage progressed, the variation rate reduced, leading to minimize losses in the quality. The microbial population also reduced significantly in comparison to fresh pulp and maintained within permissible limits. Similarly, the squash samples showed stability concerning to TSS, non-reducing sugars, pH and titratable acidity and diminishing variation rate for the remaining parameters as the storage period for the pulp progressed. The squash samples acquired sensorial acceptable till the end of storage. Among both species, Annona atemoya species responded better to storage under -200C, due to comparatively lower variation rate of biochemical parameters and equitably comparable sensorial scores. Furthermore, its quality pulp could be maintained up to 211 days as compared to 163 days in Annona squamosa L. Inclusive of all the aspects of acceptability and economic feasibility, the frozen pulp of both species can be stored for a longer duration, i.e. ten months for Annona atemoya and eight months in Annona squamosa L. and can be a boon for helping the farming community in getting reasonable prices for their second-grade produce also.

    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-07-20) KHOBRAGADE, RATIRAM ISHWAR.; Nagre, Dr. P. K.
    The investigation entitled “Genetic analysis of F1 hybrids in brinjal (Solanum melongena L.)” was undertaken at Main Garden, Department of Horticulture, Dr.Panjabrao Deshmukh Krishi Vidyapeeth, Akola. Eleven genotypes (Aruna, Bhandara local, Wadsa local, Bhatai local, Manjarigota, Chandur local, Ruchira, Krishna Kathi, White Round, DBSR-52, White Brinjal) were crossed in line x tester mating design during kharif 2013. All parents and resultant crosses with standard check Phule Arjun (F1) were evaluated during Kharif and summer season of 2014-15 in Randamised Block Design with three replications. The observations were recorded on various growth,flowering,yield and quality aspects. The parents, Bhatai local, Aruna, Ruchira, White Brinjal, Wadsa local and Chandur local, while the crosses, Aruna x Ruchira, Bhatai local x Ruchira , Aruna x Chandur local, Wadsa local x Ruchira, Bhatai local x DBSR-52, Aruna x DBSR-52, Wadsa local x Chandur local and Wadsa local x DBSR-52 were found as best parents and hybrids respectively as evident from per se performance. The analysis of variance for treatments was highly significant for all the characters over both the seasons. The variance due to parents, females, males, female x male were significant for most of the characters. Whereas the variance due to interaction of parents x season, crosses x season and (parents Vs crosses) x season were also significant for most of the characters. The analysis for combining ability revealed the significant differences due to females, males, female x males, crosses, seasons, crosses x seasons, female x seasons, male x seasons and (females Vs males) x seasons, for most of the characters. The crosses, Wadsa local x Ruchira, Wadsa local x Chandur, Wadsa local x DBSR-52, Bhatai local x DBSR-52, Aruna x DBSR-52, Bhatai local x Ruchira, Aruna x Chandur local and Aruna x Ruchira were identified as potential crosses on the basis of average heterosis, heterobeltiosis and standard heterosis; which manifested heterotic effects for growth, earliness and quality traits. Among female parents, Bhatai local, Wadsa local, Aruna and among male parents, DBSR-52, Ruchira, Chandur local were identified as good combiner for growth, flowering(earliness), higher yield and quality characters. Six crosses viz., Bhandara local x Manjari Gota, Wadsa local x Chandur local, Wadsa local x White brinjal, Wadsa local x Ruchira, Aruna x Chandur local and Bhatai local x Ruchira exhibited significant sca effects for yield per plant and yield per hectare. The crosses viz., Wadsa local x Ruchira, Wadsa local x Chandur local, Bhatai local x Ruchira and Aruna x Chandur local were identified as promising hybrids on the basis of better per se performance, high standard heterosis in desirable direction, significant sca effects and both the parents involved in these crosses had good combining ability effects for yield per plant and most of the characters studied. Additive gene action was found to be predominant for all the characters in pooled mean, except plant spread where non-additive gene action was predominant. Analysis of genetic components of variation revealed that the importance of additive gene action operating in inheritance of yield and its important components. The information on nature and magnitude of genetic makeup of yield and its components thus obtained could be useful to the brinjal breeder in formulating an efficient breeding programme to achieve desired genetic improvement in this important vegetable crop.

Nitrogen content in seed (2.25 and 2.31 %), protein content in seed (14.06 and 13.05 %) and micro nutrients like, Zinc (17.20 and 15.93 mg kg-1) recorded maximum in the genotypes CSV-29R and E-19 respectively, while other seed micro nutrients i.e., Mn (5.68 and 5.45mg kg-1), Fe (46.43 and 44.25 mg kg-1) and Copper (1.80 and 1.65 mg kg-1) recorded significantly highest in genotypes E-19 and CSV-29R respectively, than other genotypes and checks at harvest. Phule Anuradha (check) and CSV-29R were found earlier in physiological maturity. In relation with yield and yield attributes, genotype CSV-29R and E-19 noted significantly highest panicle length (18.17 and 16.63 cm), panicle diameter (7.33 and 7.20 cm), earhead exertion (74.7 and 70.5 %), number of grains panicle-1 (1544 and 1478), grain weight plant-1 (22.95 and 20.67 g), test weight (32.62 and 30.62 g), grain yield (2393 and 2090 kg ha-1), biological yield (6308 and 5844 kg ha-1) and harvest index (37.96 and 35.76 %) respectively, than other genotypes and best check M 35-1. Among the three checks, M 35-1 recorded best in performance on the basis of all traits under study than other check genotypes viz. Phule Anuradha and Ringni in moisture stress under late sown rainfed condition. Current study was also erudite for the optimization of appropriate concentration of PEG for screening the genetic resource of rabi sorghum for further detailed studies. Various osmotic stress levels had substantial effects on germination and early vegetative growth traits of rabi sorghum genotypes. At highest concentration (-0.066 MPa) of osmotic (PEG) stress condition, genotypes M-35-1, E-277 and E-227 showed positive result for shoot length, root length and seedling dry weight. Germination per cent, seedling vigour, shoot length, root length, seedling dry weight and stress tolerance index also decreases with increase in osmotic stress. Considering the correlation coefficient on grain yield found positive and significant correlation with all morpho physiological, growth and biochemical parameters except plant height plant-1. While, yield has negative significant correlation with days to 50 % flowering and physiological maturity. Traits under study viz., may be used in the breeding programme for the development of moisture stress tolerant genotypes under late sown rainfed condition for changing climatic scenario.

    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-09-11) YADAV, YOGITA MANOHAR.; Rathod, Dr. T. H.
    An experiment was conducted on “Evaluation of American cotton Genotypes for morpho-physiological and Oil parameters”, at the experimental field of Cotton Research Unit, Dr. PDKV Akola, during Kharif season of 2016-17 and 2017-18.The experiment was laid out in randomized block design with three replications and twenty seven treatments. The objectives of the experimental trial were: 1) to study the morpho-physiological and yield attributes of American cotton genotypes. 2) To study the oil parameters of American cotton genotypes. The observations were recorded on various morphological parameters viz., plant height (cm), leaf area (dm2), Total dry matter (g), physiological observations like Leaf area index, relative water content(%), Specific leaf weight (g/dm2), relative growth rate (RGR) (g/g/day), Total chlorophyll content (mg/g) and Absolute growth rate (AGR) (g/day) were recorded at 60, 90, 120 DAS and at harvest. Whereas, yield and oil parameters were also recorded per replication and treatment wise. American cotton (G. hirsutum) AKH-1303 followed by AKH-2013-2 and AKH-2013-1 recorded maximum seed cotton yield. Genotype AKH-1303 recorded more plant height (122.60 cm), leaf area (46.22 dm2), total dry matter (77.21 g), leaf area index (2.07), specific leaf weight (0.88g/dm2) over the other genotypes whereas, AKH-1301 recorded significantly more number of leaves (49.30) ) and more total chlorophyll content (1.39 mg/g) over the other genotypes. The check PKV-Rajat recorded more relative water content. With respect to yield and yield attributes, genotype, AKH-8660 took minimum days to square initiation (43.20 days) and IC-359088 (47.42 days) recorded maximum days to square initiation. AKH-31 (55 days) recorded minimum number of days to 50 % flowering over other genotypes. The minimum number of days to 50 % boll bursting was found in genotype AKH-2012-9 (109.83 days). Genotype AKH-1303 recorded significantly highest number of sympodial branches (15.73), higher number of bolls (16.47), maximum seed cotton yield (62.89 g/plant), lint yield (22.12 g/plant), seed index (10.35 g). The check AKH-8828 (41.31%) recorded best ginning percent and AKH-2012-9 recorded significantly highest boll wt. (3.12 g). Genotype AKH-081 (check) recorded maximum oil content (21.60%), while AKH-8660 showed minimum oil content (12.6%). Genotype AKH-976 recorded maximum erucic (0.84%), and linoleic acid (52.64%). Significantly highest arachidic (0.42%) and stearic acid (3.96%) were observed in genotype check variety PKV-Rajat. Significantly maximum myristic (0.90%) and palmitoleic acid (0.58%) were registered in genotype AK-32.Genotype GV-22 recorded highest palmitic acid (23.96%).Highest oleic acid (22.69%) and linolenic acid (0.31%) were recorded in AKH-8828 and AKH-1302 respectively. Analysis of variance for pooled data indicated that there were significant differences among the twenty seven genotypes. The values of PCV (Phenotypic coefficient of variation) were higher than GCV (Genotypic coefficient of variation) indicating the importance of environment on the expression of these characters. The seed cotton yield, oil and oil quality parameters showed high heritability along with high genetic advance which would be rewarding for improvement in these characters through selection. The seed cotton yield per plant exhibited positive and significant phenotypic and genotypic correlation with plant height, leaf area , total dry matter, number of days to square initiation, number of monopodia, number of sympodia, number of bolls, boll weight and lint yield. The results indicated that these characters are more related genetically.

    (Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-06-15) Authors: SANJAY, D. J.; Advisor: Ganvir, Dr. M. M.
    Abstract: The field experiment entitled “Impact of organic nutrient modules on productivity of pigeonpea based intercropping system’’ was conducted during Kharif season of 2018-19 at research farm of Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra) to find out effect of different organic integrated nutrient management on pigeonpea based intercropping systems. The experiment was laid out in Strip Plot Design (SrPD) with four main plot factors i.e. intercropping system (T1 – Sole Pigeonpea, T2 - Pigeonpea + Soybean 1:4, T3 - Pigeonpea + Foxtail millet 1:4 and T4 - Pigeonpea + Cotton 1:4) and three sub plot factors i.e. organic integrated nutrient management (N1 – 100% FYM + Vermicompost, N2 – 75% FYM + Vermicompost + 25% Neem cake and N3 – Control) replicated three times. The varieties adopted are PKV-Tara (pigeonpea), AMT-1001 (soybean), Co 1 (foxtail millet) and AKA-7 (cotton). Plant height (cm) was higher in pigeonpea + cotton (1:4) intercropping system. Number of leaves plant-1 was not influenced by the intercropping system. Leaf area, leaf area index and number of branches was maximum at 120 DAS in pigeonpea + foxtail millet (1:4) intercropping system. Number of root nodules and root volume of the pigeonpea crop, dry matter accumulation plant-1 (g) and root dry matter accumulation plant-1 (g) was more in sole pigeonpea. Total leaf biomass added (kg ha-1) and total biomass added for in-situ decomposition (kg ha-1) was higher in pigeonpea + soybean (1:4) intercropping system than other intercropping system. Number of pod plant-1, number of seed plant-1, seed yield (kg ha-1), stalk yield (kg ha-1) and total uptake of NPK (kg ha-1) was found higher in pigeonpea + soybean (1:4) intercropping system. Among organic integrated nutrient management treatment 75% FYM + Vermicompost + 25% Neem cake significantly influenced dry matter accumulation in plant (g) at 90 and 120 DAS, root dry matter (g) at 90 DAS, number of pod plant-1, number of seed plant-1, grain yield (kg ha-1), stalk yield (kg ha-1) and NPK uptake. Pigeonpea + Soybean (1:4) intercropping with organic integrated nutrient management of 75% FYM + Vermicompost + 25% Neem cake was found significantly higher seed yield (kg ha-1), pigeonpea equivalent yield (kg ha-1), system productivity (kg-1 ha-1 day-1), net monetary returns, B:C ratio and system profitability (Rs.-1 ha-1 day-1). Quality parameters viz. protein content (%), protein yield (kg ha-1), oil content (%), oil yield (kg ha-1) were also found higher values in pigeonpea + soybean (1:4) intercropping system. In brief, OINM combination of 75% FYM + Vermicompost + 25% Neem cake in pigeonpea + soybean (1:4) intercropping treatment recorded higher PEY and economic returns.

    (Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-06-15) Authors: SANJAY, D. J.; Advisor: Ganvir, Dr. M. M.
    Abstract: The field experiment entitled “Impact of organic nutrient modules on productivity of pigeonpea based intercropping system’’ was conducted during Kharif season of 2018-19 at research farm of Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra) to find out effect of different organic integrated nutrient management on pigeonpea based intercropping systems. The experiment was laid out in Strip Plot Design (SrPD) with four main plot factors i.e. intercropping system (T1 – Sole Pigeonpea, T2 - Pigeonpea + Soybean 1:4, T3 - Pigeonpea + Foxtail millet 1:4 and T4 - Pigeonpea + Cotton 1:4) and three sub plot factors i.e. organic integrated nutrient management (N1 – 100% FYM + Vermicompost, N2 – 75% FYM + Vermicompost + 25% Neem cake and N3 – Control) replicated three times. The varieties adopted are PKV-Tara (pigeonpea), AMT-1001 (soybean), Co 1 (foxtail millet) and AKA-7 (cotton). Plant height (cm) was higher in pigeonpea + cotton (1:4) intercropping system. Number of leaves plant-1 was not influenced by the intercropping system. Leaf area, leaf area index and number of branches was maximum at 120 DAS in pigeonpea + foxtail millet (1:4) intercropping system. Number of root nodules and root volume of the pigeonpea crop, dry matter accumulation plant-1 (g) and root dry matter accumulation plant-1 (g) was more in sole pigeonpea. Total leaf biomass added (kg ha-1) and total biomass added for in-situ decomposition (kg ha-1) was higher in pigeonpea + soybean (1:4) intercropping system than other intercropping system. Number of pod plant-1, number of seed plant-1, seed yield (kg ha-1), stalk yield (kg ha-1) and total uptake of NPK (kg ha-1) was found higher in pigeonpea + soybean (1:4) intercropping system. Among organic integrated nutrient management treatment 75% FYM + Vermicompost + 25% Neem cake significantly influenced dry matter accumulation in plant (g) at 90 and 120 DAS, root dry matter (g) at 90 DAS, number of pod plant-1, number of seed plant-1, grain yield (kg ha-1), stalk yield (kg ha-1) and NPK uptake. Pigeonpea + Soybean (1:4) intercropping with organic integrated nutrient management of 75% FYM + Vermicompost + 25% Neem cake was found significantly higher seed yield (kg ha-1), pigeonpea equivalent yield (kg ha-1), system productivity (kg-1 ha-1 day-1), net monetary returns, B:C ratio and system profitability (Rs.-1 ha-1 day-1). Quality parameters viz. protein content (%), protein yield (kg ha-1), oil content (%), oil yield (kg ha-1) were also found higher values in pigeonpea + soybean (1:4) intercropping system. In brief, OINM combination of 75% FYM + Vermicompost + 25% Neem cake in pigeonpea + soybean (1:4) intercropping treatment recorded higher PEY and economic returns.

    Title: EFFECT OF DIFFERENT DECOMPOSING CULTURE ON QUALITY OF COMPOST FROM WEED BIOMASS.
    (Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-08-05) Authors: PANDULE, DNYANESHWAR SANJAY; Advisor: Paslawar, Dr. A.N.
    Abstract: The study was aimed to explore the possibility of conversion of different available weed biomass to utilize the embedded nutrients for supplying enriched organic manure for better soil health and crop growth, which will not only improve the yield and quality of the produce but also conserve energy, minimize pollution, save foreign exchange and improve the fertilizer use efficiency and subsequently that will help to revitalize and restore the soil fertility and will revive the microbial activities for sustainable crop production. An experiment on, “Effect of different decomposing culture on quality of compost from weed biomass” was carried out during August to November in year 2018-19 at Centre for Organic Agriculture Research and Training (COART) Farm, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola with twelve treatments as different weed biomass viz., of Cassia tora, Sorghum helepense, Parthenium hysterophorus and some other species of weed replicated thrice in Factorial Randomized Block Design by using different decomposing cultures like S-9 culture, PDKV culture and Dung slurry. The periodical chemical analysis carried during weed composting indicated decrease in pH, total organic carbon, C:N ratio while increase in nutrient content and microbial population with the advancement of composting. Composting samples were collected and analyzed for chemical and biological properties at different stages viz., 30, 60, 90 DAF tanks and at maturity (differed with different treatments). Initially the maximum temperature (47.2 0C) was recorded in Parthenium hysterophorus followed by 45.6 in mix weed, 45.1 0C in Sorghum helepense and 44.8 0C in Cassia tora compost at 3 weeks after filling of compost pits. Further the temperature was steadily decreased towards maturity. Among the three decomposing culture PDKV culture recorded highest temperature followed by S-9 and dung slurry. It was revealed that Sorghum helepense weed biomass indicated statistically higher reduction of about 32.69 kg over initial weight added in compost pit of 60 kg at start of filling of compost pit. However, Cassia tora recorded less reduction in weight of about 29.13 kg. Mix weed recorded reduction in weight of about 31.80 kg and Parthenium hysterophorus recorded reduction in weight of about 31 kg over initial weight of material added in compost pit of 60 kg. Among four weed biomass, the pH was significantly highest in mix weed during composting (7.38 at 30 DAF and 7.92 at DAF respectively). At maturity, EC of mix weed compost was significantly lower than other weed compost. At maturity stage mix weed compost showed significantly maximum reduction (20.58 %) in total organic carbon while the lowest C:N ratio (15.13: 1) was recorded with mix weed compost. Mix weed compost was rich in total N (1.36 %), P (0.65 %) and K (0.59 %) followed by Cassia tora, Parthenium hysterophorus and Sorghum helepense compost. Among the different weed biomass, compost obtained from mix weeds recorded significantly maximum bacterial, fungal and actinomycetes population at maturity.
